新买的nc4400笔记本，装了ubuntu 6.06.1，发现cpu频率调节不能用，一直以最高频率运行。
Gnome的applet提示：
CPU frequency scaling unsupported
You will not be able to modify the frequency of your machine. Your machine may be misconfigured or not have hardware support for CPU frequency scaling.
插入speedstep-centrino模块提示：
$ sudo modprobe speedstep-centrino
